SPECIFICATION forming part of Letters Patent No. 764,1 16, dated July 5,1904.

Application filed March 10, 1904. Serial No. 197,507.

(No mode;

To (LZ/ whom it may concern Be it known that I, PHILIP T. DODGE, ofWashington, District of Columbia, have invented a new and usefulImprovement in Linotype-lVIaehines, of which the following is aspecification.

My invention has reference to the Morgenthalerlinotype and kindredmachines, wherein a printing-slug or linotype is castin aslotted moldagainst a line of matrices temporarily closing the face of the same, thetypemetal being delivered into thc'mold at the rear from theperforated'or slotted mouth of the melting-pot, which acts directlyagainst and serves to close the mold.

The object of my invention is to reduce the weight of the linotypes andthe amount of metal contained therein by forming cavities in the basethereof; and to this end itconsists in providing the mouth or throat ofthe pot through which the molten metal is delivered with one or morestuds or projections adapted to enter the mold and serve the ofiice ofcores therein, the studs being of such form that they may be withdrawnfrom the mold and from the slug without disturbing the latter. Thesestuds or cores may be of any sectional form and of any suitable length,provided only they are adapted to be readily withdra n from the mold andthe slug therein. "he openings for the admission of metal may bethrough, between, or in one side of the cores, as preferred.

1n the accompanying drawings, Figure 1 mold of a linotype-machine withthe matrices and my improved pot-mouth in operative relation thereto.Figs. 2and 3 are respectively a face view and a cross-section of a mouthpiece in accordance with my invention. Fig.

4 is a view illustrating the same in an alter-' native or equivalentform. Figs. 5 and 6 are perspective views illustrating linotypesproduced by my improved mechanism.

Referring to Figs. 1, 2, and 3, A represents a slotted mold wherein thelinotype B is cast. This mold may be of any ordinary or suitable formand construction.

C represents the matrices alined tempora- I rily against the face of themold in order that their cavities or matrices proper may form thecorrespondingcharacters in relief on the edge of the linotype.

D- represents the delivery mouth or throat through which the moltenmetal is delivered into the mold from a source of supply. Thisdelivery-throat may be integral with the pot, as in the ordinaryMcrgenthaler machine, or it may be independently movable, as in othermachines, the only requirement being that it shall connect with a supplyof molten metal and means for delivering the same under suitablepressure into the mold.

The mold and the delivery-mouth will be movable one in relation to theother, as usual in this class of machines, so that the mouth may beseated against'the base of the mold to close the same during the castingoperation and the parts there-after separated to permit the ejection ofthe linotype. Up to this point the parts may be constructed and arrangedtooperate in the ordinary manner.

In carrying my invention into effect I form on or apply to the mouth Din any suitable manner one or more projections or cores E, adapted toextend into the mold from the rear without closing or filling the same,so that when the linotype is cast these cores will produce cavities oflike form in its base. They may be varied in length and in sectionalform at will, provided only they leave at the base of the slug asuiiicient body of metal to give it the requisite stability when in use.i

In the form shown in Figs. 1, 2, and 3 the mouthpiece, adapted toproduce a slug such as shown in Fig. 5, is of a dovetail form incross-section and is driven endwise tightly into a corresponding groovein the pot-mouth, as is usual in linotype-machines. or studs shown inFigs-1, 2, and 3 are separated from each other lengthwise of themouthpiece in order that the sing or linotype may be solid from one sideto the other be-- tween the cavities, as shown in Fig. 5.

The holes F, through which themolten metal is delivered, may be locatedbetween the cores or projections or extended through the melting-pot orother' The cores 2 be readily removed.

. slug and that the cores, or both. The cores may be locatedso as to lieeither at the top or the bottom of" the mold cavity' in order to producein the slug open cavities 1n one side or face, as shown 5 in Fig. 6.

It will be understood by the skilled .me-

chanic that the studs may be made integral with the mouthpiece orseparately formed and As it is a common practice to use a mouthpiecesecured thereto in any suitable manner.

of maximum length in connection with a mold which is variable in lengthin order to cast linotypes of different lengths,the separatelyformedstuds or cores may be screwed into 5 the mouthpiece or otherwiseattached in order that one or more of them may be removed when the moldis shortened in length.

In Fig. 3 I have shown the cores as screwed into the body of themouthpiece that they may other part is employed. between the mold and sthe pot. The slag is left undisturbed in the mold, so, that itmay betrimmed to the exact mane height required in the usual manner by a knifeacting across the face of the mold.

Having described my invention, what I claim is- 4 1. In alinotype-machine, a slotted mold in combination with a melting-pothaving its delivery-mouth adapted to act directly against and close thebase of the mold, and provided with one or more studs adapted to enterthe mold and to be withdrawn from the mold and from the slug therein.

2. As a new article of manufacture, a mouthpiece for a linotype-machine,adapted to fit directly against and close the rear face of the mold, andprovided with perforations for the passage of the metal, and with one ormore studs adapted to enter the mold and to be Withdrawn therefrom and.from the slug therein.

3. In a linotype -machine, a mouthpiece adapted to close the rearprovided with studs adapted to enter the mold and to be withdrawnendwise therefrom and from the slug therein.

In testimony whereof I hereunto set my hand, this 5th day of February,1904, in the presence of two attesting witnesses.
